menu / navigation class

All - I'm looking to see if anyone knows of a php class for menu navigation. I'm looking for a pure php / html solution and would like to have the following features: bread crumb trails like: "Home >> Level 1 >> You are here" tree style menu navigation (unlimited levels) tree layout not dependent on html file and directory structure menu item highlighting based on $PHP_SELF Okay, so I'm asking for a lot. I'm looking at phplib's tree class and the new menu class in phplib 0.7. (it's broken). I've also poked around looking for at a few other solutions but they mostly looked like hacks for the environment they were developed in. If no one can turn up anything then I guess I'll start building a class to meet the above requirements. -- Scott
